The catalysts were characterized by XRD, TEM, TPD, TPR, and XPS. The support effect of metal oxides (Al2O3, SiO2, ZrO2, and TiO2) revealed that Cu-Ni supported on Al2O3 showed the highest activity for EL hydrogenation to ethyl 4-hydroxypentanoate (EHP) and the subsequent intramolecular esterification of EHP to GVL. EHP intramolecular esterification to GVL in the ethanol solution was a reversible reaction with an equilibrium constant of 24 at 453 K. A simplified reaction kinetic network was established. The solvent had a significant influence on the reaction equilibrium and the catalyst stability. Cu-Ni/Al2O3 in n-hexane solvent gave a higher GVL yield than that in ethanol solvent, and showed better recyclability than that in toluene solvent. With optimizing the conditions, Cu-Ni/Al2O3 gave 99.9% conversion and 98% selectivity to GVL with a space–time yield of 1.13 gGVL gcat-1h?1 in n-hexane solvent with good recyclability.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryIn the present study, the ratio of reducing to oxidizing (F/O) elements as an indicator for maximum oxygen interference during the solution combustion synthesis (SCS) process of ZnO particles was determined using simple mathematical calculations. The obtained result was called special point (S.P). To interpret the role of S.P in the SCS reactions, ZnO particles were synthesized in the presence of citric acid, hexamine, hydrazine, and urea with various F/O values (0.75, 1, 1.25). The correlations between the S.P, physicochemical properties of the synthesized ZnO powders, and density functional theory (DFT) predictions were investigated. X-ray diffraction results, band-gap values, oxygen vacancy data, DFT results, and S.P points demonstrated the direct relation of these parameters. According to the S.P idea, it can be affirmed that the structural defects, particle size, optical band-gap (Eg = 3.06), the color of the products, the magnetic properties (0.2 emu/g), and the antibacterial inhibitory (15.625 μg/mL) of the synthesized particles were controlled via the interference of O2 during the synthesis process. In fact, the S.P investigation was suggested that the reaction rate of the combustion synthesis process could regulate the properties of ZnO particles.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryOxygen-deficient tungsten oxide is one of the promising materials for broad applications due to its enhanced characteristics owing to the oxygen-deficiency. Development of a mass production process is crucial in consideration of the increasing demand of this material in industrial purposes. A continuous screw reactor was employed to the production of oxygen-deficient tungsten oxide. The effects of hydrogen concentration and the reduction time on the composition of products were investigated. The maximum WO2.72 mole fraction of 0.95 was achieved by optimum hydrogen concentration and reduction time. X-ray Photoelectron Spectroscopy (XPS) spectra of the products indicated the introduction of oxygen-deficiency. Anisotropic crystal growth in the (010) direction is found in the cross-section observation by Scanning Electron Microscope (SEM). The displacing value from High-Resolution Transmission Electron Microscope (HR-TEM) demonstrated the existence of WO2.72. The reaction kinetic was investigated by thermogravimetric analysis. Estimated activation energy supported the results from the continuous process. This work suggests the promising process for the large-scale production of functional materials.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryThis study reports an aqueous-based continuous finishing strategy to introduce durable and rechargeable antibacterial, antifungal, and antiviral functions onto polyester fabrics. A series of water-soluble acyclic N-halamine precursors, poly(methacrylamide-co-acrylic acid) (PMAs), were synthesized and finished onto poly(ethylene terephthalate) (PET) fabrics by crosslinking with poly(ethylene glycol)-based water-soluble epoxy resins through a simple continuous dip-pad-dry-cure procedure. Amide groups in the PMA on the finished PET were converted to stable N-halamines by treating with diluted chlorine bleach. The influences of reaction conditions on the finishing were evaluated, and the finished PET fabrics were characterized with Fourier transform infrared (FT-IR) spectroscopy, iodometric titration, water contact angle evaluation, fluorescence microscopy, scanning electron microscopy (SEM), and energy dispersive X-ray spectrometry (EDS) analysis. The N-halamine finished PET fabrics provided potent and rapid biocidal efficacies against Gram-positive bacteria, Gram-negative bacteria, fungi, and viruses, and inhibited the formation of bacterial and fungal biofilms. Moreover, the finishing did not negatively affect the physical and mechanical properties of the PET, making the new process attractive for a broad range of related functional finishing of synthetic fabrics.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryNepenthes pitcher-inspired slippery surface provides an alternative strategy to overcome the shortcomings of the current superhydrophobic surfaces such as thermal–mechanical stability and functional durability. Herein, we fabricate a lubricant-infused slippery surface (LISS) through micro-nano structure building, low surface energy molecular grafting and perfluoropolyethers (PFPE) lubricant oil infusion. The surface morphologies, chemical compositions, wettability, dynamic liquids movement, self-cleaning, anti-corrosion behavior, and thermal–mechanical stability were investigated and analyzed. The electrochemical impedance spectroscopy (EIS) results reveal that the fabricated LISS exhibits enhanced Rct and |Z|0.01Hz values with 2 orders of magnitude higher even after 30 days immersion, demonstrating outstanding long-lasting anti-corrosion properties. Besides, the LISS also exhibits superior capacities of hot water repellency (～90 °C water droplets) and scratching resistance. We believe these results have significant implications for understanding the design and multi-functional applications of biomimetic liquid-infused slippery materials.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryAn integrated process of esterification with phosphotungstic acid/poly (ether sulfone) (PWA/PES) membrane, transesterification with alkalized polysulfone (APSF) membrane and Graphene Oxide/poly (vinylidene fluoride) (GO/PVDF) separation membrane was carried out to produce biodiesel from acidic oil. At the first step, the PWA/PES membrane was introduced to catalyze the esterification reaction. The morphology, maximum pore size, porosity and catalytic esterification performance of PWA/PES membrane were investigated. After the esterification, products and reactants without reaction were put into the GO/PVDF separation membrane to soybean oil and other substances. The permeation mixture flux and soybean oil rejection of the GO/PVDF separation membrane is 597.89 L/m2·h and 98.02%, respectively. At the second step, the APSF membrane was added to catalyze the transesterification reaction in which the soybean oil reacted with methanol. The results showed that the esterification conversion was 98.6% and transesterification conversion was 91.2%. The main parameters of the biodiesel product obtained meet the Chinese Standard (GB/T 20828) and European Standard (EN 14214).

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryMany efforts have been devoted to develop both cathode and anode materials with high energy and power densities. In this paper, one-dimensional (1D) Li-rich Li1.17Ni0.35Mn0.48O2 (0.4Li2MnO3?0.6LiNi0.7Mn0.3O2, LLMNO) cathode and carbon-coated MnO (C@MnO) anode active materials synthesized with the same 1D MnC2O4 precursor nanowires (NWs) were fabricated for use in full lithium-ion batteries (LIBs). As-prepared 1D LLMNO was used as a LIB cathode, which delivered a high capacity (215.8 mAh g?1), improved cyclic lifetime, and notable rate capability. Furthermore, the 1D C@MnO anode exhibited an enhanced capacity (1001.4 mAh g?1), high cycling stability, and excellent rate capability, in comparison with MnO NWs without carbon decorations. While the full LIB consisted of 1D structural LLMNO cathode and C@MnO anode, it showed a high capacity above 178.5 mAh g?1 from 0.1 to 4.2 V at the first cycle. The enhanced Li+ storage properties suggest that these full LIB configurations with 1D LLMNO and C@MnO NWs could be a prospective candidate for practical LIB applications.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryThe removal of elemental sulfur from the final leach residue produced during the atmospheric oxidative leaching of chalcopyrite concentrates is both a technical and an economic challenge. Lanxess Lewatit? AF 5 catalyst is a promising candidate material that can collect this elemental sulfur during the leaching process. However, to be cost-effective it is necessary to develop methods to regenerate and recycle the AF 5. In the present research, toluene and tetrachloroethylene were studied as potential organic solvents for the removal of the sulfur from the sulfur loaded AF 5. Also, the recovery of elemental sulfur from the resulting liquor was investigated. The effects of temperature, time and AF 5 to solvent ratio on sulfur removal from the sulfur loaded AF 5 were examined. The optimum desulfurization conditions were 100 °C for toluene and 110 °C for tetrachloroethylene for an AF 5 to solvent ratio of 1:50 and a processing time of 120 min. For toluene and tetrachloroethylene, the sulfur removals were 89.8% and 88.1%, respectively. Toluene was considered to be the most promising solvent due to its higher sulfur removal efficiency and a reduced effect on the behavior of the recycled AF 5 in the leaching process. After three consecutive leaching and regeneration cycles the sulfur absorption capacity and the copper and iron leaching recoveries were essentially unchanged. Copper and iron recoveries of greater than 95% and greater than 80%, respectively, were achieved with the recycled AF 5.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryHydrogen bonds, which can be divided into many types along with the deepening of research, exist in many compounds and have certain impact on properties of substances. In this work, effect of intramolecular hydrogen bond on solvent resistance of polymeric membranes was studied from two aspects. On the one hand, the existence of intramolecular hydrogen bond on solvent resistance of polymeric membranes was studied by constructing and shielding special hydroxyl groups in typical polymer polyurethane. On the other hand, content of intramolecular hydrogen bond on solvent resistance was investigated by building different ratios of inter- and intra-molecular hydrogen bonds in polyvinyl alcohols. The structures, solvent resistance and hydrogen bonding interactions were systematically investigated by FT-IR, XRD, Ds and performances before and after immersed in solvents. Permeabilities of the membranes for practical application were also characterized. The results showed that distinct type and ratio of hydrogen bonds played different role on solvent resistance. A good agreement between the swelling performances and content of intramolecular hydrogen bond proved the positive effect of intramolecular hydrogen bond on solvent durability of polymeric membranes. In addition, polyurethane membranes exhibited good impermeability to water vapor, oxygen and chloride ions which showed potential application in many fields.

    查看更多>>摘要：? 2021 The Korean Society of Industrial and Engineering ChemistryDeep-blue fluorescent materials are a key component in the development of organic light emitting diode (OLED). The synthesis of efficient deep-blue luminescent materials with narrowband emissions and stable OLED devices is important. Here, three new deep-blue fluorescent materials containing electron donor as an indenocarbazole and π-bridge linkage as a pyrene moiety were designed and synthesized. They possessed high thermal decomposition temperature higher than 498 °C. The three new fluorescent dopants, 1,6-DICP (1,6-bis(7,7-dimethylindeno[2,1–b] carbazol-5(7H)-yl)pyrene), 1,7-DICP (5,5′-(pyrene-1,7-diyl)bis(7,7-dimethyl-5,7-dihydroindeno [2,1–b]carbazole)), and 1,6-DIC-3,8-DIP (5,5′-(3,8-diisopropylpyrene-1,6-diyl)bis(7,7-dimethyl-5,7-dihydroindeno[2,1–b]carbazole)) were synthesized and doped in 2-methyl-9,10-bis(naphthalen-2-yl)anthracene as a blue host for emitting layer. The devices fabricated with these emitting materials showed deep-blue emission with peak wavelength (λem) at 445, 445, and 446 nm [CIE (1931): (0.15, 0.09), (0.15, 0.09), and (0.149, 0.085)]. It also exhibited high color purity with narrow spectral width (FWHM: 59 nm). In addition, they showed high external quantum efficiencies (EQE) of 3.61, 4.97, and 8.34%, respectively. In particular, the 1,6-DIC-3,8-DIP-based device exhibited high EQE and high current and power efficiencies, owing to the high photoluminescence quantum yield (PLQY) presumably due to a suppression of molecular aggregation by structural modification to give a twisted structure with a high dihedral angle.
